    Protein Summary

    This Bacteroides thetaiotaomicron protein contains two repeats of the Acyl-CoA N-acyltransferase (Nat) fold, a 3 layer alpha/beta/alpha fold with a mixed central beta sheet. Overall topology, with the NAT domain duplication accompanied with the internal swap of C-terminal strand of one of the domains, is similar to that of FemX peptidyltransferase (1ne9), which is involved in the synthesis of the bacterial cell wall, by catalyzing the addition of amino acid(s) on the peptidoglycan precursor using aminoacylated tRNA as a substrate. Significant structural similarity (3A RMSD over 265 aminoacids) between the B. thetaiotaomicron protein and FemX protein 1ne9, suggests possible functional similarity of these two families, despite very low sequence similarity (~6% seq id).
